coordsys.units - Function

1.1.3 Recover the units for each axis


Description

Each axis associated with the Coordinate System has a unit. This function returns those units (in world axis order).

You can recover the units either for all coordinates (leave type unset) or for a specific coordinate type (mimumum match of the allowed types will do). If you ask for a non-existent coordinate an exception is generated.

You can set the units with function setunits.
